We know that many Universities and companies are working on Robots to be used in Farming , we know as I type this Robots are used on Farms to Milk Cows Clean Barns preform remote viewing and filling of Water tanks in remote fields.
I myself saw a prototype do cleaning duties of a complex nature with the staff of the exhibit telling of the hours of labor saved. Know that time is money.
More interesting today I heard a Podcast on Robots being designed by The Australian Center of Field Robotics that in time will be able to not only go to check the status of a crop, apply inputs, treat for pests and when ready harvest a crop! Wow think of the Labor savings that in turn saves money a lot of money a hell of a lot of money.
That is key, if a greenhouse can be paid for in the harvest of a season simply think of the money saved in labor and increased production.
Bogus the mind.
As I write this I can not help but think that in Basement shops University labs and even at John Deere Robots are being worked on for the Hemp industry.
If I was you and had money that is what I look to invest in,
